Seledonia´s is a must! The food is amazing, and very unique to traditional cuisine in Peru (there are two dishes I haven´t seen anywhere else in Cusco: picante de alpaca and picante de queso). The restaurant is a family run place, where you can some nights meet the whole family.The presentation is at par with other gourmet places in Plaza de Armes, but the prices can not be found anywhere else for the excellent food. All dishes are made to order, and the drinks are cheap and strong. I will be going back!
